ABSTRACT

The world over, it is indisputable that the introduction of computer technology in different facets of life, has virtually transformed and entranced information processing, which is very vital in any organization or parastatals of government. Not only as a means of information processing, the technology has also proved to be the fastest means of information retrieval, which forms the nucleus of this study.
This work tries to x- ray the rate role of the computer in crime investigation as it affects the Nigerian police. Force it looks at ways of improving the information management of the force. This research work will cover the following areas: record information retrieval relating to MIS (Management information system), retirement Cretan for officers and crime mapping through a data bank of crime related information.
A detailed design of a computerized approach that will bring the much needed innovation is given. Also included in this work is a praper documentation for the new system design.

CHAPTER ONE

INTRODUCTION
Information Technology (IT) has set a new world order turning the world into a global village, where information plays an indispensable role.
The Federal Investigation and Intelligence (FIIB), is a special outfit of the Nigeria police force, as a role similar to that of the FBI (Federal Bureau of intelligence) of the united states (US) information they say is an indispensable force, and if we should go by this maxim, it buttresses the need at which classified information is to this outfit.
Over the years, this outfit had made tremendous impact in combating crime, but in recent times, there has been an avalanche of crime wave in the country leading to insecurity of life and properties close investigation concerning crime activities reveals that this special outfit of the police force is bedeviled with obsolete equipment.
Despite the glint strides taken by this outfit over the years changing their investigation and recording equipment to tape storage using cassette as recorder, there are still a lot of surmountable problems which has hitherto, reduced the efficiency Bureau, Ogbor-Hill, Aba and other division of the outfit through out Nigeria. The panacea to this may no doubt; lie in the introduction of a properly designed computer base system which will bring the much-desired automation hence, a prerequisite for being a member of the new world order vis-à-vis information technology.

1.1 STATEMENT OF THE PROBLEM
The statutory duty of the federal investigation and intelligence Bureau (FIIB) is crime prevention and intelligence network which is solely based on information. This information received from conducted investigation, which should be supplied to the Bureau within minutes using electron communication. But this takes days or weeks and sometimes months if the investigation is carried in a distant area. The storage medium currently at disposal for information is susceptible to unauthorized access and damage. Most often, the recorded information is usually not within the reach when needed. Going by this high level of graft in the country, officers can easily remove: recorded information of a very serious crime activity by mere bribe offer. In view of the above problems w3hich have attracted the author’s attention, he has unequivocally, decided to design a computer base system which will correct this abnormalities.

1.2 PURPOSE OF THE STUDY
Having been aware of the numerous anomalies which have reduced the efficiency of the Nigeria police force (NPF), the purpose of this research is focused on designing an developing a computerized based or approach to information storage and retrievals against the manual approach, as it affects the (FIIB) federal intelligence investigation Bureau), and the Nigeria police in general.

1.3 AIMS AND OBJECTIVES
The aims and objectives of the research work centers on the following:-
– To show case the merits of a computerized system in police investigation and intelligence.
– To upgrade the information network system of the Nigeria police force
– To enhance speedy and reliable information retrieval in crime records.
– To identify areas where computers can be used in detective work.
– To investigate the possibilities of using the computer to analyse and compare substance taken from the scene of crime.
– To establish the possibilities of using the computer in crime mapping – A situation where data concerning crimes that have been committed in a certain area is fed into a computer and then, the computer produces a map that shows whether it is any pattern to the crime.

1.4 SCOPE OF THE STUDY
This research work is limited to the federal investigation and intelligence Bureau (FIIB) Ogbor-Hill Aba, Abia state although this outfit has just been moved to Calabar, Cross River State. The choice of investigation and intelligence was chosen due to the fact that there are certain information, which are not meant for public consumption.

1.4 LIMITATION
Investigation for facts about this research work was fraught with the following constraints.
Issue of confidentiality:
This work is a dicey one that concentrates on issues considered confidential. The outfit chosen for investigation could not disclose or rather give access easily to the relevant information. Investigation and intelligence needs high level of secrecy. Sequel to the approval for data collection comes after services of consultation with important personnel of the command.
TIME:
Time factor is another major constraint, which unequivocally did force me to limit the scope of the work. The time stipulated for actual completion of this work is rather too short to cover all relevant sections of the command. Also, the researcher had to spend some time before approval for investigation was given.
FINANCE
Intended to make comprehensive excerpts from some foreign journals on issues bothering on crime investigation and intelligence network but due to financial constraint, I could only limit myself to a few within my reach. Also, the cost of shuttling to the new area command of the outfit also constituted a big source of financial stress.
